In earthworms, each segment can move independently, so that alternating contractions between the two different sets of muscles in many different segments create shape changes all along the body. This produces accordion-like body movements that help the worm push through soil and maneuver through small spaces within

When the circular muscles contract, the earthworm stretches, becoming longer and thinner. The earthworm uses its setae to anchor the front of its body in the soil. Now the longitudinal muscles contract and the earthworm becomes shorter and wider or it bends from one side to the other, pulling the body forward.

If the extracellular fluid has an excess of sodium ions, a. sodium ions move into cells b. intracellular fluid moves to the outs
Mandarinka [93]

Answer:

b. intracellular fluid moves to the outside of cells

Explanation:

The presence of an excess of sodium ions in the extracellular fluid would make it hypertonic with respect to the intracellular fluid. The concentration gradient would drive the intracellular fluid towards the outside of the cell to balance the concentration of the fluids on either side. The passive movement of fluids occurs across the cells and is driven by the concentration gradient only. The biological membranes are permeable for fluid movement such as the movement of water across it.
